Configuration:

Issuer: https://token.actions.githubusercontent.com
Repository: hanzoai/desktop
Owner Filter: hanzoai

Service Account

Email: [email protected] Purpose: GitHub Actions authentication for EV code signing

Permissions:

Workload Identity User (for GitHub Actions)

KMS Configuration

Location: us Keyring: hanzo-apps Key Name: EVCodeSigning Algorithm: RSA 4096 SHA-256 Full Path: projects/hanzo-inc/locations/us/keyRings/hanzo-apps

GitHub Secrets Required

The following secrets should be configured at: https://github.com/hanzoai/desktop/settings/secrets/actions

Already Configured

✅ EV_CODE_SIGNING_CERTIFICATE - The public certificate (.cer file)
✅ TAURI_PRIVATE_KEY - Tauri updater private key
✅ TAURI_KEY_PASSWORD - Tauri updater key password

No Additional Secrets Needed

The workload identity federation handles authentication automatically - no service account keys needed!

To Import Your EV Certificate Private Key to KMS

If you have the EV certificate private key (from hanzo-412316 or elsewhere), import it:

# First, export the private key from the old location or certificate file
# (You would need access to the old hanzo-412316 project or the original cert)

# Then import to the new KMS key:
gcloud kms keys versions import \
    --location=us \
    --keyring=hanzo-apps \
    --key=EVCodeSigning \
    --algorithm=rsa-sign-pkcs1-4096-sha256 \
    --import-job=YOUR_IMPORT_JOB_NAME \
    --rsa-aes-wrapped-key-file=wrapped-key.bin \
    --project=hanzo-inc

Note: If you don't have the private key from the old setup, you'll need to:

Generate a new CSR from this KMS key
Submit to your certificate authority to get a new EV certificate
Store the new public certificate in the EV_CODE_SIGNING_CERTIFICATE GitHub secret

Verification

Test the setup with:

# Check workload identity pool
gcloud iam workload-identity-pools describe github \
    --location=global \
    --project=hanzo-inc

# Check service account bindings
gcloud iam service-accounts get-iam-policy \
    [email protected] \
    --project=hanzo-inc

# Check KMS key
gcloud kms keys describe EVCodeSigning \
    --location=us \
    --keyring=hanzo-apps \
    --project=hanzo-inc

Current Status

✅ Workload Identity Pool created
✅ OIDC Provider configured for GitHub Actions
✅ Service Account created and bound
✅ KMS Keyring and Key created
✅ Permissions granted
✅ Workflow updated to use hanzo-inc
⚠️ EV Certificate private key needs to be imported to KMS (or new cert generated)
